During the walk Friday night, Wallenda's team was in contact with him, and remind him to make sure the truck didn't catch on the wire pendulums and pull him backwards.

He never had to remove it and was asked after completing his high-wire walk about how the harness worked.

"It was definitely there," said Wallenda. "It was something that I was very nervous about every time I crossed over a pendulum. It was something that was on my mind and I would kind of pause for a minute but I made it across successfully."
